Be it known that we, J 0H1; L. KENDALL, of Fox borough,State 'of Massachusetts, and Rrommn H.

TBESTED, of J amaica,'in-the State of New York, have invented anew and improved Compound to be Used as a Coating for Textile Fabrics, Paper, 850.; and we hereby declare the following to be a full, clear, and exact description th'ereof. V

Our invention consists of a new and improved compound, tobe applied as a facing-or coating to buckramframes, and similar textile fabrics, and to paper.

The compound consistsof the following ingredients, and is prepared in the following manner, namely:

First, white French zinc or its equivalent, or lead, I

is ground in any colorless and inodorousoihwe preferring caster-oil...

I The following preparation we have found to answer an excellent purpose in: practice, namely, to every pound of zinc or lead,'six oiinces of the oil. This may be somewhat varied, without very materially afiecting the result obtained by the use of this compound.

Then we proceed as follows} To each pound of ether, -add two-thirds of an ounce of gun-cotton, such cotton being first saturated with a sufilcient quantity of alcohol to cause the cotton to dissolve in 'the ether, which gives us a collodionsuitable for ourpurpose, although the quantity of cotton may beincreased, to the extent of an ounce to the pound, without afiecting' the quality of the collodion for our use, excepting that it would be of too much consistency. V

Then, to every pound of zinc-or lead, so ground, add

twenty ounces of the collodion, so prepared, this being about the proportion that should be used, in proportion to the amount of. oil given above, in which the zinc or lead is ground, in order to produce well, inthe use of this compound, the results hereinafter stated.

These are now well mixed together, and the compound obtained'is a thin paste or paint',.of an extreme whiteness. I 1 This is to he used in this condition, or can be colored to any desired shade, by, merely adding the proper mineral colors.

In the manufacture of hats of a certain class, this: compound is to be applied, in one-.layerat a time, to

the frame of buckram, or other textile fabric, with theaid' of a brush, as rapidly as possible, and it driesalmost instantly after being so applied, and the frames.

can at once pass on, after receiving the desired amount of coating, to the dies, in which they are" finished-by being stamped up to imitate straw goods, or goods of other configuration. Generally, two coats will give the fabric a sufiiciently heavy and even surface .forthis p p r i By the'use of this compound, invthe obtaining of a sinface on hat and bonnet-frames of buckram', or other textile fabric or material, the drying-room, 01*," fact,-

any kind of artificial heat, is dispensed with, su'chcom pound drying on the surface almost immediately after being applied by a brush, or in any other convenient way, by the action of the atmosphere, which-saves a vast amount of time and spacefor drying-purposes, and expense atten' t thereon; and the fabric has a soft, polished surface, is pliable, capable of being struck This coating can also be applied .to paper requiring up in dies without injuryto such surface, and is watera-surfaee having qualities above described,--but if the paper is very absorbent, it would be well to protect it from the action of the oil of the compound-by coating it first with a thin to limit ourselves to the specific proportions given, as these may be varied somewhat; but, in so .varyin'g them, it must be borne in mind that too much oil makes the compound too' sticky, and too little will make it peel or fallofl' the surface of the fabric coated; and enough collodion should be added to the compound to make it ofsuflicient-thickness to permit of its being laid on the fabric,in a single coat at 'a time, rapidly, and also,.at the same time, to cause the oil thereinto be rapidly evaporated. Oollcdion used by photographers will'eflect the object, but -not in as. great a degree as In the preparation of ourcompound, we do not the collodio'n prepared substantially as above stated.

It hasbeen found, in practice, that one skilled person can paint, every day, about eight'hundred bonnet or hat-flames, three coats-each, so. rapidly does'the surface, or coating applied, dry, and become finished for the dies in which they are finished for the market.

What we'claim as new, and desire to byter's Patent,

1. The compound, composed of- French zinc or -its equivalent, or lead," oil, and collodion, substantially as and for-the purposes herein described.-

' 2. The compound, composed ofthe substances in the proportions substantially as and-for the here:

in described. a
